Hard Break

You seem to have alot of knowledge with the MB, and I dont want to affend your inteligence but did you make sure that the main vacuum line from the vacuum pump to the booster is intact and not loosing vacuum from there? I drove a W112 one time and it didn't have that on and the break was almost rcok hard.

This may be one of those problems that I never care enough about to fix. I think most cars have one after a modicum of mileage is attained, so it isn't too bothersome!

I really have never gotten out to even check it beyond opening the brake resoivoir and making sure there was fluid(yeah-- it'd be soft if there weren't enough...)

One day!

Maybe thursday!

I seem to remember reading something on this FORUM once before that said there is no vacuum on the other side of this seal but the ol memory is not so good any more... so I hope this is your problem. If you isolated the "hissing" to the booster area, you should also be able to determine iF it is coming from around the base of where the master cylinder mounts !?
Here is what our sponsor shows it to look like:
... and here is the details of the part:
Those aren't the o-ring you a looking for.

The pinion seal is the seal that seals the differential and the driveshaft.
